EEek that looks some ferocious complicated I have to input the camera angle for each frame? or do I just put in fov number and it follows the con or?
If you haven't already done so, check out the tutorial posted earlier by DeeACE. Basically, play your film to a point where you want your camera to be, then pause it. Bring up the shot setup window and "Grab All" for start and end if you want the camera stationary through the shot. Choose "World Pointing" (or "World Relative"; it's been a while and I don't remember) and a target, then the camera will follow that target plane throughout the shot.
For an easy flyby setup, pause your film about halfway through what you want as your shot. Use the arrow keys to move your view outside your plane (off to the side and either slightly up or down works well). Then "Grab All". Set your start time and end time accordingly, like start and end 10 seconds from "now". Then when you play it back, you'll have a nice 20 second shot of a flyby.
Mess around with the FOV for other effects.
